At a time H1N1 influenza has heightened awareness and concern about the spread of infectious diseases, two British companies — BAE Systems and Quest International UK — have announced new technology to inhibit the spread of pathogens on board aircraft.

The AirManager cabin air management system “eliminates all airborne viruses and bacteria,” according to a news release posted on BAE’s website. The company also writes:

The patented AirManager uses a revolutionary Close Coupled Field Technology (CCFT) – a contained and safe electrical field that eliminates smells, and breaks down and destroys airborne pathogens, contaminants and toxins.

BAE says it has successfully tested the filtration system on eight BAe 146 and Avro RJ aircraft. Both of these models are regional passenger jets. The company is currently conducting trials in much larger Boeing 757 jetliners and expects to design similar filters for use in two workhorses of commercial aviation — the Boeing 737 and Airbus A320.

Even before H1N1, airline cabin air quality had come under scrutiny. Because jet engines have to work harder to pull in fresh air from outside, many aircraft recycle cabin air to reduce fuel costs. The practice has caused considerable debate within the aviation industry and the medical community as to whether it increases the transmission of disease.

BAE officials claim their AirManager will allow air conditioning systems to operate even more efficiently — essentially paying for the system in fuel conservation within the first year of use.

Meanwhile, on the ground, the Washington Metro Area Transit Authority has begun weekly cleaning of common areas to reduce the spread of flu among its estimated 1 million daily passengers. For more on that, and other H1N1-related information, see my Liveshots Blog.
